Two natural enemies of ash whitefly (Siphoninus phillyreae), jntroduced into California in 1990, proved effective in Southern California field trials, completely controlling this Dest in release sites within -24 months, Evaluations in release sites in Central and Northern California, Arizona and Nevada look equally promising.
